Keyboard brightness commands only work after 'Sleep', Latitude E5410
This has been going on for ages. Upon a fresh boot, keyboard brightness dimming does not work until I put laptop to sleep. Then, the FN+up/down works fine. I can't remember if this has always been the case, but I know when I first got my laptop, Win7 pre-installed, the auto-dimmer was working. Now I am not sure it is (not that I mind, I don't want it on). Now, when I check Advanced Power Options, the "enable auto dimmer" isn't even listed.
I pretty much need to have quick brightness keyboard control due to my light sensitivity. Win+X is annoying to resort to.
Also, when the FN+up/down keys DO work to change the brightness, it says:
"Ambient Light Sensor Disabled". If that helps for anything. (Also also, I checked, and I have no "sensors" installed, so says my system.)
Also, my keyboard has a FN+Auto Dimmer key that is the 'left' key in the arrow set, but it doesn't appear to do anything. Or am I completely missing that THIS might be what I need to hit in order to enable keyboard dimming commands? (I haven't tried, but right now, after coming out of Sleep mode, the dimming commands are working and the "auto" option does nothing).
Anyway....

Don't know what else you need to know.
I did some searching online and this might be a BIOS setting, but I didn't want to go that route before I talk to someone.
(PS, Power Options, as far as I can tell, only lets me manually, on the screen, adjust brightness - it seems to have no control over keyboard adjustment settings).
Thanks in advance.
